Elevated isolation of reconfigurable data flow resources in cloud computing

A data processing system, comprising:

• a pool of reconfigurable compute and memory resources, comprising:
• arrays of configurable compute and memory units arranged in one or more reconfigurable processors, wherein the configurable compute and memory units comprise reconfigurable datapath elements having programmable interconnections and configurable logic functions, and wherein computational operations performed by the reconfigurable datapath elements are defined by configuration data loaded from configuration files,
• memory units located outside of the arrays of configurable compute and memory units, and busses coupled between the memory units and the arrays of configurable compute and memory units;
• and
• a runtime processor, comprising a user space and a kernel space, wherein the kernel space is exclusively authorized to execute predetermined privileged operations on the pool of reconfigurable compute and memory resources, and further comprises first and second channels, implemented by the arrays of configurable compute and memory units, between the user space and the kernel space, wherein the user space is configured to transmit commands for the kernel space through the first channel, and wherein the kernel space is configured to transmit results to the user space through the second channel, operatively coupled to the pool of reconfigurable compute and memory resources and configured to:
• load a first configuration file comprising first configuration data that defines first computational operations to be performed by the reconfigurable datapath elements for executing a first user application to a first subset of the arrays of configurable compute and memory units in the pool of reconfigurable compute and memory resources,
• assign a first subset of the memory units to the first user application,
• load a second configuration file comprising second configuration data that defines second computational operations to be performed by the reconfigurable datapath elements for executing a second user application to a second subset of the arrays of configurable compute and memory units in the pool of reconfigurable compute and memory resources,
• assign a second subset of the memory units to the second user application,
• start execution of the first and second user applications on the first and second subsets of the arrays of configurable compute and memory units, respectively,
• wherein the kernel space further comprises a resource manager that is configured to track, during execution, a first allocation of the first subset of the memory units and the first subset of the arrays of physical configurable units to the first user application and a second allocation of the second subset of the memory units and the second subset of the arrays of configurable compute and memory units to the second user application;
• and wherein the arrays of configurable compute and memory units are further configured, duration execution, to retrieve the commands from the first channel, to perform validation of parameters of the commands against the first and second allocations, to process the commands in response to the parameters of the commands passing the validation, and to submit results from processing the commands to the second channel.
